Description
In the Linux kernel, the following vulnerability has been resolved:ksmbd: unset the binding mark of a reused connection
Steve French reported null pointer dereference error from sha256 lib.
cifs.ko can send session setup requests on reused connection.
If reused connection is used for binding session, conn->binding can
still remain true and generate_preauth_hash() will not set
sess->Preauth_HashValue and it will be NULL.
It is used as a material to create an encryption key in
ksmbd_gen_smb311_encryptionkey. ->Preauth_HashValue cause null pointer
dereference error from crypto_shash_update().
BUG: kernel NULL pointer dereference, address: 0000000000000000
